Problems solved by technology

[0003] The main function of the power steering pump bracket is to fix the steering pump on the engine and convert the energy input by the engine into steering oil pressure. Although the hydraulic power steering system has been widely used in ordinary cars, in hybrid cars, Due to the change of the relative position of the engine and the steering pump, the existing power steering pump bracket cannot meet the requirements of the best position of the engine and the steering pump, and is prone to the problem of vibration and shedding of the steering pump, which affects the energy conversion between the two, so , a new bracket structure is required to meet these requirements

Embodiment Construction

[0011] see figure 1 , The steering oil pump bracket is composed of two parts, the U-shaped oil pump mounting seat 1 on the upper part and the idler wheel mounting seat 2 on the lower part, and is an integral structure. There are three bolt holes 11 for installing the oil pump correspondingly on the two side walls of the U-shaped oil pump mounting base 1, and a groove 12 for letting the wheel shaft pass is opened on the side wall on the side where the oil pump drive wheel is installed. Bolt holes 13 connected with the engine are arranged outside the U-shaped bottom. The idler mounting seat 2 is located at the side lower part of the U-shaped oil pump mounting seat 1, and is positioned at the same side position where the oil pump driving wheel is installed, and the idler mounting seat 2 has a waist-shaped groove 21 for installing the idler wheel.

[0012] see figure 2 The steering oil pump 3 is fixed in the U-shaped oil pump mount 1 of the bracket by three bolts, and the axle ...

Abstract

This invention discloses one mixed power automobile rotation fuel pump racket, which main body is of one u shape fuel pump fixing socket with two side walls opened with fuel pump screw holes and with one side opened with concaved tank through fuel wheel axle and the U shape fuel pump is fixed on the bottom with motor screw hole fixed. Besides the U shape fuel pump is fixed down the socket on same side of drive wheel with one inertia fix socket with kidney slot fixed.

Description

technical field [0001] The invention relates to a fixing bracket, in particular to a power steering pump bracket used in a hydraulic power steering system of a hybrid electric vehicle. Background technique [0002] At present, the steering of hybrid electric vehicles adopts relatively mature hydraulic power steering technology. Its basic working principle is to use engine power to drive the oil pump to work. The oil pump extracts the power steering fluid from the oil storage tank and outputs it to the power steering gear. In the direction of steering, the power control valve in the power steering gear controls the hydraulic pressure difference between the two sides of the power cylinder in the input power steering gear to generate power assistance, reducing the hand force of the steering wheel when driving and steering. [0003] The main function of the power steering pump bracket is to fix the steering pump on the engine and convert the energy input ...
