Embodiment Construction

[0018] A specific embodiment of the present invention provides a wheel hydraulic pump 15, such as figure 1 and figure 2 As shown, it includes a stator 1, a rotor 2 and a vane 3, the vane 3 is arranged on the rotor 2, an oil outlet 4 and an oil inlet 5 are arranged on the stator 1, and the stator 1 is fixedly connected with the axle 6 of the vehicle, The rotor 2 is fixedly connected coaxially with the hub 7 of the wheel 22 .

[0019] During the energy recovery process, the rotating hub 7 will drive the rotor 2 to rotate, the rotor 2 compresses the hydraulic oil to the hydraulic accumulator 10, and the kinetic energy becomes hydraulic energy for storage; The high-pressure hydraulic oil drives the hydraulic motor 13 to rotate, and the hydraulic motor 13 drives the wheel hub 7 to rotate through the gearbox 20 and the transmission shaft 21, converting hydraulic energy into kinetic energy.

Abstract

The invention provides a hub hydraulic pump, a kinetic energy recovery and release system and a vehicle. The hub hydraulic pump comprises a stator, a rotor and vanes, the vanes are arranged on the rotor, the stator is provided with an oil outlet and an oil inlet, the stator is fixedly connected with the axle of the vehicle, and the rotor is coaxially and fixedly connected with the hub of a wheel. According to the hub hydraulic pump, the kinetic energy recovery and release system and the vehicle, the hub hydraulic pump, the axle and the hub are fixedly connected, the kinetic energy of the vehicle can be recycled, and is released when needed, the energy transferring and converting process is simplified, the energy is small in loss in the transferring process, and the hub hydraulic pump, the kinetic energy recovery and release system and the vehicle have the advantage of being simple in structure.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a wheel-side hydraulic pump, a kinetic energy recovery and release system and a vehicle. Background technique [0002] Existing car must increase certain resistance to prevent automobile from moving ahead to whole car when needing to stop. The traditional method is to step on the brake pedal, and the brake caliper is driven by the brake pedal to fasten the brake disc, so that the wheels stop rotating. The wheel changes from the original rolling to the sliding of the wheel tire relative to the ground. Since the sliding friction coefficient is much greater than the rolling friction coefficient, it can reduce the parking time required for the car to stop. However, when the brake pedal is stepped on, the car generally still has a certain speed, and if there is speed, there is kinetic energy; the traditional car braking system converts this part of energy into heat energy through th...
