Problems solved by technology

[0003] For large heavy-duty non-hydraulic walking vehicles, when the traditional brake system encounters a continuous steep slope, the brake system will continue to work, and the temperature will rise, which will easily lead to brake failure, which is currently an unsolvable problem

Embodiment Construction

[0017] For the convenience of explanation, the following is combined with the figure 1 , a vehicle deceleration method and a deceleration device invented are described in detail.

[0018] A method for reducing the speed of a vehicle, using the running vehicle to drive the gear pump 1 to work, thereby driving the hydraulic oil in the gear pump 1 to move, using the control valve 2 to control the flow rate of the hydraulic oil per unit time, and reversely controlling the flow rate of the gear pump 1 Rotating speed, utilize the rotating speed of gear pump 1 again to control the form speed of vehicle.

[0019] The flow rate of the hydraulic oil per unit time is controlled by a solenoid valve group; the power source of the gear pump 1 is the large toothed plate 4 in the rear axle box 3, the transmission shaft on both sides of the large toothed plate 4, and one of the wheels Or several, generally this technical scheme is mainly used on the rear axle main shaft of main vehicle rear a...

Abstract

The invention discloses a vehicle speed reduction method and device, a running vehicle drives a gear pump 1 to work so as to drive hydraulic oil in the gear pump 1 to move, a control valve 2 is usedfor controlling the flow speed of the hydraulic oil in unit time, the rotating speed of the gear pump 1 is reversely controlled, and then the form speed of the vehicle is controlled through the rotating speed of the gear pump 1. According to the method, a specially designed vehicle speed reduction is utilized; the rotating speed of the gear pump is controlled through the amount of the hydraulic oil conveyed by the gear pump in unit time, meanwhile, the running speed of the vehicle is controlled, the purpose of speed reduction is achieved, meanwhile, damage to an original brake system is reduced, and therefore the running safety is improved, and the speed reduction device is reasonable in structural design, high in stability, convenient to use and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of vehicle speed control, in particular to a vehicle speed reduction method and a speed reduction device. Background technique [0002] As we all know, the current vehicle braking system mainly includes disc brakes and drum brakes, some use mechanical transmission brakes, some use hydraulic transmission, and some use pneumatic transmission, but no matter which transmission mode, the principle of braking is basically the same. [0003] For large heavy-duty non-hydraulic walking vehicles, when the traditional brake system encounters a continuous steep slope, the brake system will continue to work, and the temperature will rise, which will easily lead to brake failure, which is also a problem that cannot be solved at present. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a vehicle deceleration method and a deceleration device for the deficiencies ...
