Abstract

An automobile angle steering gear comprises a box, single-row quill bearings without cage and connecting gear shafts. The two connecting gear shafts which are perpendicular to each other and are meshed with each other are arranged in the box. The top ends of the meshed ends of the two connecting gear shafts are provided with the single-row quill bearings without cage, deep groove ball bearings, snap springs and framework oil seals are sequentially arranged in bearing seats located on the parts, at the other ends of the meshed ends, of the connecting gear shafts, and bearing seats penetrate through the connecting bearing shaft to be connected with the box through dust covers, and protective sleeves are arranged at the positions, located on the outer sides of the dust covers, of the connecting gearing shafts. According to the automobile angle steering gear, a straight-through forced filling oil cup is arranged at the position of the included angle of the two connecting gear shaft, oil leakage is avoided, and oil filling is convenient to achieve. The connecting gear shafts are integrally designed, the spiral direction of spiral bevel gears on the connecting gear shafts is leftward, and the pressure angle is 20 degrees. Matching grinding is performed on the spiral bevel gears, and therefore rotation noise is lowered. The stability of product quality is improved, and the replacement period is prolonged. The requirements of users for anti-fatigue and torsion resistance of products are met.

Description

A kind of automobile angle deflector

Technical background

The utility model relates to automotive field, particularly relates to the angle deflector of a kind of automobile.

Background technology

According to related documents retrieval, the angle steering gear for cars that Chinese large-sized passenger vehicle uses at present, major part is to rely on import, the angle deflector price comparison of import is expensive, while particularly use, needs a large amount of products-supplys, not so be in short supply, will have a strong impact on the production of automobile.And the angle deflector of import is in actual use, also often there is the phenomenon of leakage of oil, particularly in the situation that moment of torsion is larger, also there will be loosening, the de-hidden danger such as split of snap ring.And the automobile angle deflector of domestic production not only exists leakage of oil, or refuel difficulty, and attachment tooth wheel shaft conical gear with axle for to separate design, profile of tooth is straight-tooth, often rupture, the problem that service life is low, has increased user cost greatly.

Summary of the invention

The purpose of this utility model will provide the angle deflector of a kind of automobile exactly, and it can overcome the above problem that prior art exists.The purpose of this utility model is to realize like this, a kind of automobile angle deflector, comprise casing, single-row without retainer quill bearing, attachment tooth wheel shaft, it is characterized in that: in casing, be provided with two vertical also attachment tooth wheel shafts of engagement mutually, the top of the end of engagement of two attachment tooth wheel shafts is provided with single-row without retainer quill bearing, in bearing seat on the other end attachment tooth wheel shaft of end of engagement, be disposed with deep groove ball bearing, jump ring, outside framework oil seal, and connected with casing through attachment tooth wheel shaft by cover of dust, on the outside attachment tooth wheel shaft of cover of dust, be provided with protecting sleeve.

Angle α between two described attachment tooth wheel shafts has two kinds of 90o, 120o, and is prepared by corresponding casing.

Described attachment tooth wheel shaft is unit design, and the trochoid spiral gear hand of spiral on attachment tooth wheel shaft is left-handed, and angle of obliquity is 20o.

The utility model arranges through type forced filling oil cup in two attachment tooth wheel shaft angles, not only oil tight, and it is also convenient to refuel.And attachment tooth wheel shaft is unit design, the trochoid spiral gear hand of spiral on attachment tooth wheel shaft is left-handed, and angle of obliquity is 20o.Trochoid spiral gear grinds through pairing, has reduced rotation noise, has reduced rotary damping moment≤0.3N.m.Improve the stability of product design, and extended the cycle of changing assembly for user vehicle.The antifatigue of user to product and the requirement of torsion are met.

Brief description of the drawings

Fig. 1 is the utility model structural representation;

1. casing, 2. single-row without retainer quill bearing, 3. attachment tooth wheel shaft, 4. deep groove ball bearing, 5. jump ring, 6. bearing seat, 7. outside framework oil seal, 8. cover of dust, 9. protecting sleeve, 10. through type forced filling oil cup.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail;

A kind of automobile angle deflector; comprise casing 1, single-row without retainer quill bearing 2, attachment tooth wheel shaft 3; it is characterized in that: in casing 1, be provided with two vertical also attachment tooth wheel shafts 3 of engagement mutually; the top of the end of engagement of two attachment tooth wheel shafts 3 is provided with single-row without retainer quill bearing 2; in bearing seat 6 on the other end attachment tooth wheel shaft of end of engagement, be disposed with deep groove ball bearing 4, jump ring 5, outside framework oil seal 7; and connected with casing 1 through attachment tooth wheel shaft 3 by cover of dust 8, on the outside attachment tooth wheel shaft 3 of cover of dust 8, be provided with protecting sleeve 9.

Angle α between two described attachment tooth wheel shafts 3 has two kinds of 90o, 120o, and is prepared by corresponding casing.

Described attachment tooth wheel shaft 3 is unit design, and the trochoid spiral gear hand of spiral on attachment tooth wheel shaft 3 is left-handed, and angle of obliquity is 20o.

When concrete enforcement, two attachment tooth wheel shaft transmitting ratios are 1:1; Static test: apply≤500N.m is quiet to be turned round, lost efficacy without any heap part; Unloaded moment :≤0.35N.m.After two attachment tooth wheel shaft processing, be coated with anti-corrosion oil at active flank, the trochoid spiral gear of debugging when general assembly on two attachment tooth wheel shafts makes its smooth running, flexible.In casing centre bearer, fill lithium base grease.The utility model serviceability temperature is at-40 DEG C to+80 DEG C.Owing to being provided with trochoid spiral gear on attachment tooth wheel shaft, it turns to consistent with input end hand of rotation, and is provided with bearing at its two ends, so it is not easy fracture, and can bear larger moment of torsion, and does not produce any card machine phenomenon.Prior art is to adjust gear clearance with packing ring, and the utility model is designed to threaded shaft bearing sleeve adjusting gear gap, has improved degree of regulation, has avoided noise.Inner ring at cover of dust is provided with outside framework oil seal, at the roughness at attachment tooth wheel shaft outside framework oil seal place, increases polishing, can effectively prevent leaking of the interior lithium base grease of casing, has thoroughly solved the phenomenon of Vintage Product easy oil leakage, has extended the replacement cycle.
