Abstract
The invention provides a steering tube column assembly for an electric automobile. The steering tube column assembly comprises an upper steering column tube (2), a lower shaft (4) and a universal joint assembly (6), wherein a needle roller bearing (3) and a roll bearing (5) are sleeved on the upper steering column tube (2); a steering wheel end spline (1) is arranged at the end part of the upper steering column tube (2); and the needle roller bearing (3) and the roll bearing (5) are directly fixed on an automobile body. The steering tube column assembly disclosed by the invention is compact in structure, small in space occupied by volume and light in weight; and the consumption of energy sources can be effectively reduced and the driving mileage is increased.
Description
Technical field
The present invention relates to a kind of electronlmobil steering swivel system, particularly relate to a kind of electronlmobil column assy.
Background technology
The developing goal that " the automobile industry adjustment and the development planning " of putting into effect according to country proposes; China will form new-energy automobile production capacities such as 500,000 pure electronic, charged type hybrid powers and coventional type hybrid power in 3 years from now on, and the new-energy automobile sales volume accounts for about 5% of manned vehicle total sales volume.And will realize this goal, the support of government's policy favourable will be ev industry is able to stable development in present stage the strongest driving.
The spare and accessory parts producer of the battery-driven car automobile accessories maturation that is far from, part factory is few, and reliability is still to be tested, the adequate and systematic service ability.So produce this piece at the electronlmobil steering column, majority all is to adopt existing little car steering column to substitute, and mainly comprises turning to column jecket, lower shaft and universal joint assembly; Turn to and be set with needle bearing and ball bearing of main shaft on the column jecket; The column jecket peripheral hardware has axle sleeve on turning to, and adopts anchor ear and car body to fix on the axle sleeve, and this structure is comparatively loaded down with trivial details and heavy; Applicability does not meet the operating needs of battery-driven car, does not meet the requirement of battery-driven car loss of weight.
Summary of the invention
Technical matters to be solved by this invention be the electronlmobil requirement compress the steering column parts to greatest extent volume and weight to improve its flying power.
The objective of the invention is to realize as follows: a kind of electronlmobil column assy; Comprise and turn to column jecket, lower shaft and universal joint assembly; Turn to and be set with needle bearing and ball bearing of main shaft on the column jecket; Turning to the upper prop tube end is bearing circle end spline, it is characterized in that described needle bearing and ball bearing of main shaft directly are fixed on the car body.
The invention has the beneficial effects as follows:
1, simple in structure, volume takes up room little;
2, in light weight, can effectively reduce energy resource consumption, improve travelled distance.
Description of drawings
For content of the present invention is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, to the further detailed explanation of this novel do, wherein:
It shown in the accompanying drawing structural representation of the present invention
Among the figure: 1, bearing circle end spline 2, turn to column jecket 3, needle bearing 4, lower shaft 5, ball bearing of main shaft 6, universal joint assembly
The specific embodiment:
With reference to accompanying drawing; A kind of electronlmobil column assy; Comprise and turn to column jecket 2, lower shaft 4 and universal joint assembly 6; Turn to be set with needle bearing 3 and ball bearing of main shaft 5 on the column jecket 2, turning to column jecket 2 ends is bearing circle end spline 1, and described needle bearing 3 directly is fixed on the car body with ball bearing of main shaft 5.During action, turn to column jecket under the drive of bearing circle, to rotate, transmission of power is realized turning to function to universal joint assembly.According to the actual operating needs of electronlmobil to column assy, the present invention can design and adopt the aluminum alloy materials structure is that main body constitutes the assembly parts, and low cost of manufacture belongs to environmental protection practicality product.
Above-described specific embodiment; The object of the invention, technical scheme and beneficial effect have been carried out further explain, and institute it should be understood that the above is merely specific embodiment of the present invention; Be not limited to the present invention; All within spirit of the present invention and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
