36results about How to "Reduce braking force" patented technology

In the specification and drawing a new brake system and a two-wheeled vehicle using the same are described. The new brake system includes a first brake to apply a first brake force on a first wheel ofa vehicle and transfers the first brake force to physically actuate a second brake to brake a second wheel of the vehicle. A transmission device is disclosed to transfer the first brake force to actuate the second brake.

A hydraulic brake sealing device comprises an oil pressure seat, a brake handle, an oil pressure rod, a connecting rod, a sliding pipe sleeve and an elastic member, wherein the oil pressure seat is provided with an oil pressure chamber and an assembling chamber communicated with the oil pressure chamber; one end of the brake handle is pivoted with the oil pressure seat and is correspondingly assembled at the outside of the assembling chamber; the oil pressure rod is assembled to the oil pressure chamber and the assembling chamber movably; a working head located in the oil pressure chamber, an assembling head located at the outside of the assembling chamber, a first sealing section and a second sealing section both connected to the assembling head and the working head in sequence are arranged at one end of the oil pressure rod; two ends of the connecting rod are assembled to the brake handle and the assembling head of the oil pressure rod respectively; the sliding pipe sleeve is arranged in the assembling chamber in a sliding manner and is fixedly sleeved to the first sealing section; the elastic member comprises an assembling part arranged on the working head, an actuating part and two deformation sections connected between the assembling part and the actuating part. When a driver brakes suddenly, the hydraulic brake sealing device can retard braking force and avoids accidents caused by the sudden brake such as deadlock and slipping of wheels relative to the ground surface.

The present invention relates to a super capacitance assembly energy storage type electric motor speed regulation tractor hoist. The tractor hoist consists of a three-phase alternating-current supply air switch, a charge power supply module, a capacitance assembly energy accumulator, a DC speed regulation module, a control panel, a main electric motor, a clutch, a gear shifting box, a power drive system, a winch clutch, a winch, an auxiliary brake clutch, an exceeding type clutch, an auxiliary brake DC motor, a charger, an energy accumulator, a bottom car system, a hydraulic system and a derrick system. The input and output ends of the three-phase alternating-current supply air switch are connected with an external power supply and the charge power supply module respectively; the charge power supply module, the capacitance assembly energy accumulator, the DC speed regulation module and the main electric motor are connected sequentially; the main electric motor is connected with the winch through the clutch, the gear shifting box and the power drive system in order; and an auxiliary brake system consisting of the auxiliary brake clutch, the exceeding type clutch and the auxiliary brake DC motor is arranged on the other end of the winch in order. The tractor hoist which has a reasonable design and reliable work can save energy, reduce energy consumption, and avoid damages on an electric network caused by a pulse power supply due to discontinuous power utilization.
