5results about How to "Increase braking power" patented technology

The application discloses a brake footboard device and a vehicle, which comprises a mounting bottom plate, a brake valve, a brake footboard mechanism and an angle detection module. The valve top of the brake valve extends upward from the mounting bottom plate. The brake footboard module of the brake footboard mechanism is installed on the mounting bottom plate through a first overturning installation module. The pressing member is arranged on the lower side of the brake footboard module and faces the valve top. The brake footboard module overturns downward and drives the pressing member to press the valve top under the action of the foot pedal force. The brake footboard module overturns upward and returns to the initial posture under the condition that the foot pedal force is removed. The angle detection module is used for brake control of the transmission system of the vehicle according to the downward overturning angle of the brake footboard module. The pedal stroke and the brake force curve are close to the ideal linear relationship, the power transmission path is simple, the energy loss is small in the transmission process, the brake force is prevented from being greatly attenuated, the advantages of electric control and mechanical brake are combined, the brake force is quickly improved, and the brake distance is shortened.

A plunger-type booster brake pump equipped with a one-way valve includes a housing assembly and a plunger assembly. The plunger assembly includes a plunger, a plunger sleeve, and a cup. One end of the plunger sleeve is movably disposed within the inner cavity of the housing assembly, forming a first volume chamber between the plunger sleeve and the inner cavity of the housing assembly. The cup divides the inner cavity of the housing assembly into a second volume chamber and a third volume chamber. A plunger cavity is provided at one end of the plunger adjacent to the plunger sleeve. The plunger cavity has first through holes evenly distributed around its axis that communicate with the second volume chamber, and a one-way valve is provided at the end adjacent to the first volume chamber. During operation, the plunger-type booster brake pump shortens the stroke and increases braking force by controlling the connection and disconnection between the first and second volume chambers through the one-way valve. At the same time, it avoids the pressure drop in the first volume chamber caused by the connection between the first and third volume chambers, solving the problem of the downward bending inflection point in the pedaling force curve and ensuring the braking safety of tractors or large motor vehicles.

This utility model relates to the field of automotive brake technology and discloses a composite heat dissipation brake assembly, including a brake disc with multiple heat dissipation holes on its surface and ventilation ribs inside. A bracket is located on one side of the brake disc, and a top cover is located at the upper end of the bracket. Friction pads are located on the lower side of the top cover and inside the bracket, and the friction pads are disposed on the upper and lower sides of the brake disc. A caliper body is located on the upper side of the top cover and is connected to the friction pads. A cooling mechanism is located inside the bracket and communicates with the interior of the friction pads. This design has the advantages of reducing the maximum temperature of the brake caliper during operation, increasing braking force during prolonged braking, and reducing braking distance. It solves the problem that if heat cannot be effectively dissipated, it will lead to a decrease in braking performance, thus affecting driving safety.

The application relates to an auxiliary braking system and a vehicle. The auxiliary braking system comprises an air source, a driving cylinder fixedly arranged in the inner side of a wheel arch and comprising a cylinder barrel and a piston rod, a connecting pipe for connecting the cylinder barrel with the air source, a reversing valve arranged in the connecting pipe between the driving cylinder and the air source, a guide seat fixedly connected with the wheel arch, and a brake assembly arranged on the side of the guide seat close to the vehicle wheel, slidably connected with the guide seat and fixedly connected with the piston rod. The brake assembly is configured to be in contact with the vehicle wheel when the driving cylinder is extended and to be separated from the vehicle wheel when the driving cylinder is retracted. The application can effectively improve the braking capacity of the vehicle and thus improve the driving safety. In addition, the driving cylinder, the guide seat and the brake assembly are arranged in the inner side of the wheel arch, so that the application has the advantages of simple structure, small space occupation and no influence on the aesthetic appearance of the vehicle.
