The invention discloses a steering and braking power-assisted system of a new energy automobile. The steering and braking power-assisted system comprises a power-assisted oil can, wherein power-assisted liquid is stored in the power-assisted oil can; an oil inlet of the power-assisted oil pump is communicated with an oil outlet of the power-assisted oil can through a power-assisted pipeline; an oil inlet of the hydraulic power-assisted brake master cylinder is communicated with an oil outlet of the power-assisted oil pump through a power-assisted pipeline; an oil inlet of the hydraulic power steering gear is communicated with an oil outlet of the hydraulic power-assisted brake master pump through a power-assisted pipeline, and an oil outlet of the hydraulic power steering gear is communicated with an oil return opening of the power-assisted oil can through the power-assisted pipeline. Wherein the hydraulic power-assisted brake master pump comprises an energy accumulator and a power-assisted piston; part of high-pressure boosting liquid pumped out by the boosting oil pump firstly enters the energy storage device to be stored; when the energy storage device is filled with the high-pressure boosting liquid and the brake pedal is treaded down, the high-pressure boosting liquid can push the boosting piston to convey the brake liquid to the wheel end brake through the brake oil pipe so as to brake the wheels. The power-assisted steering system and the power-assisted braking system are integrated, the integration level is high, the mechanism is simple, and the cost is low.
本发明公开了一种新能源汽车的转向及制动助力系统,包括助力油壶内部储存有助力液;助力油泵的进油口通过助力管路与助力油壶的出油口连通;液压助力制动总泵的进油口通过助力管路与助力油泵的出油口连通;液压动力转向器的进油口与液压助力制动总泵的出油口通过助力管路连通,液压动力转向器的出油口与助力油壶的回油口通过助力管路连通;其中液压助力制动总泵包括储能器及助力活塞;经过助力油泵泵出的部分高压助力液先进入储能器储存;当储能器被高压助力液充满,且制动踏板被踩下时,高压助力液会推动助力活塞将制动液通过制动油管输送至轮端制动器对车轮实施制动。实现了转向助力、制动助力源系统二合一,集成度高,机构简单成本较低。
