What is a Hotchkiss type rear wheel drive arrangement?
Hotchkiss Open-type Drive This arrangement (Fig. 26.26) uses two rear leaf springs, which are longitudinally mounted, and are connected to the frame by a ‘fixed’ pivot at the front, and swinging shackles at the rear. This drive, therefore, incorporates an open propeller shaft with two universal joints and a slip joint.
Which drive system is used in Hotchkiss drive?
The Hotchkiss drive is a shaft-drive system (another type of direct-drive transmission system is the torque tube, which was also popular until the 1950s).
What is Hotchkiss rear suspension?
A Hotchkiss suspension is a solid axle suspension that is commonly used on trucks for its higher load- carrying capacity (Figure 1). The suspension consists of a solid axle, two leaf springs, two shackles, and rubber bushings. The wheels are mounted at the ends of the axle. The jounce bumpers are mounted to frame.
What is the function of Hotchkiss drive?
Hotchkiss Drive: Hotchkiss drive combines the springing and positioning or locating of the rear axle. It uses a rigid axle with leaf spring mounted at its extremities as far apart as possible on the rear axle.
How does a Hotchkiss drive differ from a torque tube drive?
Hotchkiss Drive : This is the simplest & most widely used type of a rear axle drive. One end of torque is attached to the axle casing, while the other end which is spherical in shape fits in the cup fixed to the frame as shown fig:11.2. The torque tube encloses the propeller shaft.
What is it meant by torque reaction of the rear axle housing?
(mechanical engineering) On a shaft-driven vehicle, the reaction between the bevel pinion with its shaft (which is supported in the rear axle housing) and the bevel ring gear (which is fastened to the differential housing) that tends to rotate the axle housing around the axle instead of rotating the axle shafts alone.
How Hotchkiss drive is different from torque tube drive?
What is rear axle drive?
Rear drive axles are responsible for connecting the differential side gears to the drive wheels. Depending on the vehicle and the drive axle it utilizes, the rear drive axle may or may not be used to support the vehicle’s weight.
Where is Hotchkis suspension located?
Mooresville, N.C.
Located at the epicenter of motorsports engineering in Mooresville, N.C. – home to dozens of NASCAR and NHRA teams – the new facility offers custom fabrication services, safety equipment design and installation, suspension installation and racecar prep to enthusiasts and professional racers alike.
What do you mean by torque reaction?
Reaction torque is the force that acts on an object when it is not free to rotate. In the workplace setting, reaction torque usually refers specifically to the force produced by electrically powered tightening tools. Reaction torque is also referred to as torque reaction.
What is axle housing?
The Axle Housing is the case that holds the differential gears. This case is a formed steel part that is assembled using welding and machining processes.
What kind of drive is a Hotchkiss drive?
The Hotchkiss drive is a system of power transmission. It was the dominant form of power transmission for front-engine, rear-wheel drive layout cars in the 20th century. This type of drive is commonly used on passenger cars and heavy commercial vehicles.
Why are Hotchkiss springs used in heavy duty vehicles?
The springs also resist any lateral axle motions. By making the springs perform multiple duties in this way, Hotchkiss drive is very simple and thus very cheap. Since it has few parts, it’s also very sturdy, which is useful for heavy-duty vehicles like trucks.
How is the axle suspended in a Hotchkiss?
In a Hotchkiss layout, the axle is suspended by a pair of longitudinally mounted semi-elliptical leaf springs that serve to locate the axle as well as support the weight of the body. Wheel forces are transmitted to the frame and/or body through the leading (front) portion of each spring, which also serves to resist squat and axle tramp.
Which is the most common rear axle drive?
Hotchkiss drive is the most widely used type of Rear axle drive. It is also simplest compared to Torque Tube drive. In all the drives which are employed for rear axles, the springs take the weight of the body. There are many types of drives, out of which two are important. They are Torque Tube Drive.
