Abstract
The utility model belongs to automobile hydraulic steering pump assemblies and particularly relates to a shaft-connection type hydraulic power-assisted steering pump assembly for a power-driven car. The shaft-connection type hydraulic power-assisted steering pump assembly mainly comprises a hydraulic pump and an auxiliary motor, wherein a connection sleeve is sleeved on an input shaft of the hydraulic pump, and a clamping head is arranged on the end portion of the connection sleeve and clamped in a clamping groove of an output shaft of the auxiliary motor; and a connection disc is arranged between the pump body of the hydraulic pump and the casing of the auxiliary motor, and two ends of the connection disc are respectively connected with the pump body of the hydraulic pump and the casing of the auxiliary motor. The shaft-connection type hydraulic power-assisted steering pump assembly has the advantages of being simple in structure and convenient to use, related parts of the integral machine are few, and noise in operation is low; the connection sleeve for transmitting power is a machined member and is performed with thermal treatment, and the possibility in damage is low, so that the integral machine does not need frequent maintenance, and service life is long; and further, the space occupied by the integral machine is relatively small.
Description
Technical field
The utility model belongs to a kind of automobile hydraulic steering pump assembly, relates in particular to a kind of electrocar and connects formula hydraulic power-assisted steering pump assembly with axle.
Background technology
The hydraulic power-assisted steering pump of tradition auto use often is fixed on the driving engine, drives its work by crankshaft pulley through polywedge bet.For electrocar, because the main drive motor majority is one to bring out axle (this bring out axle be used to connect change speed gear box), so the hydraulic power-assisted steering pump can't drive through main drive motor.To this, most way is to adopt a helper motor, and also the mode through belt drives its work, sees that from actual condition of service complete machine has following point:
1. owing to the existence of belt, the system works noise is relatively large.
2. after work a period of time, belt can wear and tear, and needs with regularly safeguarding, with the degree of tightness of adjustment belt.
Work the long period after, the belt that need more renew.
4. the related parts of complete machine are more, and occupation space is relatively large.
Summary of the invention
The utility model provides a kind of electrocar simple in structure to connect formula hydraulic power-assisted steering pump assembly with axle to above deficiency.
The utility model solves the technical scheme that its technical matters adopted:
Axle connects formula hydraulic power-assisted steering pump assembly, mainly comprises Hydraulic Pump and helper motor, is arranged with adapter sleeve on the input shaft of said Hydraulic Pump, and the end of adapter sleeve is provided with dop, and dop is fastened in the draw-in groove of output shaft of helper motor; The input shaft of adapter sleeve and Hydraulic Pump is firmly fixed at one through the elasticity bearing pin; Be provided with terminal pad between the pump housing of Hydraulic Pump and the housing of helper motor, the two ends of terminal pad are connected with the pump housing of Hydraulic Pump and the housing of helper motor respectively.
The output shaft of described helper motor rotates through the input shaft that adapter sleeve drives Hydraulic Pump, and both are that shaft type connects, but not belt-type connects.
The beneficial effect of the utility model is: above-mentioned axle connects formula hydraulic power-assisted steering pump assembly, and it is simple in structure, easy to use, and the related parts of complete machine are less, and the operation noise is very little; Because the adapter sleeve of transferring power is a machined piece, and through heat treatment, the possibility of its damage is less, so complete machine does not need frequent maintenance, service life is very long, and the complete machine occupation space is also less relatively in addition.
Description of drawings
Fig. 1 is the exploded drawings of the utility model.
Fig. 2 is the assembly drawing of the utility model.
Among the figure:
L, Hydraulic Pump, 2, adapter sleeve, 3, the elasticity bearing pin, 4, terminal pad, 5, helper motor.
The specific embodiment
Shown in accompanying drawing, electrocar connects formula hydraulic power-assisted steering pump assembly with axle, is made up of Hydraulic Pump 1, adapter sleeve 2, elasticity bearing pin 3, terminal pad 4, helper motor 5.The pump housing of Hydraulic Pump 1 is fixed in through terminal pad 4 on the housing of helper motor 5, and terminal pad 4 is provided with the centering seam, has guaranteed that accurately the input shaft of Hydraulic Pump 1 is concentric with the output shaft of helper motor 5.Be arranged with adapter sleeve 2 on the input shaft of Hydraulic Pump 1, be firmly fixed at one through elasticity bearing pin 3 between adapter sleeve 2 and the input shaft; The end of adapter sleeve 2 is provided with dop, and dop is fastened in the draw-in groove of output shaft of helper motor 5.When the output shaft of helper motor 5 rotates, just can drive the input shaft rotation of Hydraulic Pump 1, thereby make the Hydraulic Pump normal operation through adapter sleeve 2.Because adapter sleeve 2 is machined piece, and through bakingout process, the possibility of its damage is less, complete machine does not need frequent maintenance, and service life is very long.
