Abstract

The utility model relates to a strenghthened type rear axle, including axle housing, semi-axis, brake drum and stopper, axle housing body coupling bearing frame, the bearing frame is kept away from axle housing one end and is set up the bearing mounting groove, installs double-row bearing in the bearing mounting groove, and the semi-axis is installed in double-row bearing, and semi-axis one end extends to the axle housing inboard, and the other end extends to double-row bearing and keeps away from the axle housing one end outside, and the semi-axis is located the connection pad that double-row bearing outside one end was used for installing the brake drum, connection pad fixed connection brake drum, and the stopper cover is established outside the bearing frame, and connect the brake drum, strenghthened type rear axle makes the bearing frame lengthen through the structure that changes the bearing frame to extend to between brake drum and the stopper, not only mountable double-row bearing improves the bearing capacity, The matching mode of the wheels is not changed, and the assembly of the rear axle, the vehicle and the tires is not influenced.

Description

Reinforced rear axle

Technical Field

The utility model relates to a rear axle especially relates to a strenghthened type rear axle.

Background

The conventional semi-floating drive rear axle generally used in the sightseeing bus industry has limited bearing capacity, so that the bearing capacity of the sightseeing bus is restricted.

SUMMERY OF THE UTILITY MODEL

The applicant carries out research and improvement aiming at the defects and provides a reinforced rear axle.

The utility model discloses the technical scheme who adopts as follows:

the utility model provides a strenghthened type rear axle, includes axle casing, semi-axis, brake drum and stopper, axle casing connection bearing frame, the bearing frame is kept away from axle casing one end and is set up the bearing mounting groove, installation double-row bearing in the bearing mounting groove, the semi-axis is installed in double-row bearing, and semi-axis one end extends to the axle casing inboard, and the other end extends to double-row bearing and keeps away from the axle casing one end outside, the semi-axis is located the connection pad that double-row bearing outside one end is used for installing the brake drum, connection pad fixed connection brake drum, the stopper cover is established outside the bearing frame.

As a further improvement of the above technical solution:

a sleeve is further arranged between the half shaft and the bearing seat, and an oil seal is arranged between the sleeve and the bearing seat.

The brake drum is connected with the connecting disc in a matched mode through bolts and nuts.

The utility model has the advantages as follows: the reinforced rear axle has the advantages that on the premise that the appearance of the rear axle is not changed, the structure of the bearing seat is changed, the bearing seat is lengthened and extends to a position between the brake drum and the brake, a double-row bearing can be installed to improve bearing capacity, the length of a bearing action force arm of a half axle is shortened, bearing capacity of the rear axle is further improved, and in addition, due to the fact that the connection between the rear axle and a frame and the matching mode of wheels are not changed, assembly of the rear axle, a vehicle and tires is not influenced.

Fig. 2 is the utility model provides a structural schematic of strenghthened type rear axle.

Fig. 3 is an enlarged view of a portion a in fig. 2.

In the figure: 1. a bridge housing; 2. a half shaft; 21. a connecting disc; 3. a brake drum; 4. a brake; 5. a bearing seat; 51. a bearing mounting groove; 52. a double-row bearing; 6. a sleeve; 61. and (7) oil sealing.

Detailed Description

The following describes a specific embodiment of the present embodiment with reference to the drawings.

As shown in fig. 2 and 3, the strenghthened type rear axle of this embodiment, including axle housing 1, semi-axis 2, brake drum 3 and stopper 4, axle housing 1 connects bearing frame 5, bearing frame 5 is kept away from axle housing 1 one end and is set up bearing installation groove 51, install double row bearing 52 in the bearing installation groove 51, semi-axis 2 is installed in double row bearing 52, still set up sleeve 6 between semi-axis 2 and the bearing frame 5, set up oil blanket 61 between sleeve 6 and the bearing frame 5, and semi-axis 2 one end extends to axle housing 1 inboard, the other end extends to double row bearing 52 and keeps away from the axle housing 1 one end outside, semi-axis 2 is located double row bearing 52 outside one end and is used for installing connection pad 21 of brake drum 3, connection pad 21 passes through bolt and nut cooperation fixed connection brake drum 3, stopper 4 cover is.

The strenghthened type rear axle of this embodiment, extend bearing frame 5 to between brake drum 3 and the stopper 4, the length of bearing frame 5 has been lengthened, make bearing frame 5 mountable double-row bearing 62, and shorten the distance between double-row bearing 62 to brake drum 3, half axle 2 bearing effect arm of force length has been shortened promptly, moment arm of force is the power, the calculation moment limit value of half axle 2 is unchangeable, shorten when the arm of force contracts, the power of the bearing of half axle 2 will increase, half axle 2's bearing effect diameter is corresponding extension also in addition, make the bearing capacity (anti-shear performance) of single half axle 2 further promote, further improve the bearing capacity of rear axle.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
