H-shaped power chassis

Abstract

The invention discloses an H-shaped power chassis which comprises a chassis and an engine, a clutch, a gearbox, a differential mechanism, transfer cases, chain wheel transmission mechanisms and wheels, wherein power of the engine is transferred to the differential mechanism through the gearbox and is respectively transferred to the chain wheel transmission mechanisms at both sides through the transfer cases at both sides of the chassis by a left output shaft and a right output shaft of the differential mechanism, so that the power is transferred to the wheels connected with the chain wheel transmission mechanisms at both the sides. The H-shaped power chassis has the advantages that front and rear wheels at the same sides have the same transmission ratio; and when only one of the wheels at the same side slips and the other one of the wheels at the same side does not slip, the torque can be transferred to the wheel which does not slip and a driving force is generated by an adhesive force of the wheel which does not slip, so that a vehicle successfully starts or continuously runs, and thus, the passing performance of the vehicle under the condition of a rugged pavement is improved.

Description

technical field [0001] The invention relates to a power chassis, which belongs to the field of vehicle engineering, in particular to an H-shaped power chassis. Background technique [0002] Existing automobile chassis usually consists of engine, clutch, gearbox, differential, and wheels. Among them, the power of the transmitter is transmitted to the differential through the clutch, gearbox, and drive shaft, and the differential distributes the power to The left and right half shafts drive the left and right wheels. [0003] Among them, when the differential is installed between the two front wheels of the car and distributes the power to the two front wheels of the car through the left and right axle shafts, it is called front-wheel drive. When the differential is installed between the two rear wheels of the car and distributes the power to the two rear wheels of the car through the left and right axle shafts, it is called rear wheel drive. There are also differentials ins...

AI Technical Summary

Problems solved by technology

Its disadvantages are: because the front wheels are responsible for steering and driving at the same time, the high-speed stability is poor, the driving wheel is easy to slip when going uphill, and it is easy to overturn when going downhill at high speed

The disadvantages of this type of drive are: the heavy load on the rear axle makes the car have a tendency to over-steer, the adhesion of the front wheels is small, the steering is unstable at high speeds, and the assembly and manufacturing costs are higher compared to front-wheel drive, and more faults, relatively small indoor space, etc.

However, the structure of all-wheel drive is complicated, the cost is high, the fuel consumption is large when driving on a good road, and the wear and tear of tires and parts is large.

[0007] For the above three driving modes, when one side of the wheel slips, due to the existence of the differential, the slipping wheel turns faster and faster, and the other side turns slower and slower, causing the drive axle to lose its driving force, resulting in the vehicle being unable to drive
