The oil brake assembly comprises an oil brake master cylinder 2 and a plurality of oil brake slave cylinders 1, the air brake master cylinder 4 further comprises a second air outlet end, the second air outlet end is communicated with an air inlet end of the oil brake master cylinder 2, the oil brake master cylinder 2 comprises an oil outlet end 14, and the oil brake slave cylinders 1 are communicated with the oil outlet end 14. Above-mentioned oil subassembly simple structure that stops, installation space is little, does not need other auxiliary assembly, and above-mentioned oil master cylinder 2 that stops provides fluid for oil wheel cylinder 1, for oil wheel cylinder 1 provides the power supply, plays the effect that oil braked the braking. The oil brake cylinder 1 is arranged on a brake drum or a brake disc which rotates on the rear wheel of the three-wheel excited vehicle, and the oil brake cylinder is matched with the brake part to complete the braking of the three-wheel excited vehicle. The power source of the oil brake master cylinder 2 outputs compressed gas through the second gas outlet end of the gas brake master cylinder 4, and the compressed gas pushes the piston 202 of the oil brake master cylinder 2 to act, so that the power source is provided for the oil brake master cylinder 2. Because the compressed gas through 4 exports of air brake master cylinder is as the power supply, consequently oil master cylinder 2 of stopping can set up in the position nearer with above-mentioned oil wheel brake pump 1, can overcome oil from this and stop subassembly reaction rate slow, the soft, the dynamics of brake shortcoming of low, the while front wheel is stopped through the brake subassembly of cutting off the gas earlier when braking, and then postpones to the rear wheel and pass through the oil and stop the subassembly brake, can make the motor tricycle control more easily. A first control valve 5 is connected in series between the air brake master cylinder 4 and the first air supply path 11, and the first control valve 5 is used for controlling the opening and closing of the first air supply path 11 so as to control the opening and closing of the brake. Therefore, the brake system can enable the three-wheeled motor vehicle to be fast in brake speed and good in brake effect, brake can be carried out under the condition of bearing heavy objects, and after the three-wheeled motor vehicle stops, the brake can be carried out, the brake effect is good, and the brake is stable and is not easy to fail. The five-wheel vehicle comprises a vehicle body and a brake system arranged on the vehicle body. On the basis of the original three-wheeled motor vehicle, a rear axle is additionally arranged, the original three wheels are changed into five wheels, the bearing capacity is higher than that of the original three wheels, the original two-wheel drive is changed into the existing four-wheel drive, the trafficability is better, and the three-wheel drive is particularly suitable for muddy roads, mountain roads, steep slopes and roads with extremely poor road conditions and suitable for any road surface. The stabilizing system of the vehicle body is changed from the original three wheels into the five wheels, so that the stability is better, the vehicle cannot turn over due to the fact that the turning speed is too fast, and the driving safety is improved. Braking system installs braking effect better on the automobile body of five-wheel vehicle, and the vehicle can not stop when can not be like pulling heavy goods originally, and present braking system braking effect is better, and 9 atmospheric pressure are not enough or when stopping inflating pump 10, can make the automobile body stabilize the brake, and the brake failure can not appear and lead to swift current car scheduling problem emergence.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
