Abstract

The utility model belongs to the technology of motorcycle manufacturing, in particular to a revised rear wheel felloe. A largish-diametered shallow round step is arranged outside a drive shaft hole of a rear felloe of an engine of a prior scooter, so a disc brake fails to be arranged. The utility model is characterized in that a connecting disc (11) is additionally arranged on an outer flank of the center of a rear wheel felloe (1). A disc brake (14) can be arranged on the outer flank of the connecting disc through a screw and the components of a connecting plate (6) can be arranged inside the shaft hole of a central step of the connecting disc (11). The connecting disc (11) can be connected with the prior bolt of the rear wheel felloe (12) or moulded into one body with the rear wheel felloe. Because the connecting disc is additionally arranged on the outer flank of the center of the rear wheel felloe, the utility model solves the problem that a disc brake and double shock absorbers can be arranged on the prior drum-brake wheel felloe. Moreover, the installing position for the prior drum brake is not changed, and the utility model can be arranged alone or arranged together with the drum brake simultaneously, thereby enhancing security.

Description

Dish, the bulging general-duty motor cycle rear wheel rim of stopping

Technical field:

The utility model belongs to the motor bike manufacturing technology, particularly the improvement of rear rim.

Background technology:

The above pedal motorcycle driving engine of discharge capacity mostly is the GY6 type at present, its rear rim of braking drove and makes the big slightly shallow round platform rank of diameter outside the Shaft hole after adaptive back hung single bumper and rouses the type of stopping, in order to assembling gusset piece assembly, and disc brake (as shown in Figure 1) can't be installed.And existing double damping type motor bike limits because of rear rim on the market, and what the gusset piece assembly was used is the single-row annular ball bearing structure of indeterminate state, and bearing is very short service life.Can't solve the anti-lock problem, safety performance is unreliable in addition.

Summary of the invention:

The utility model purpose is that design a kind ofly can be installed safer, comfortable disc brake apparatus not changing under the GY6 h type engine h standing state, and double damper can be installed, and prolongs the gusset piece assembly motor cycle rear wheel rim in used bearing service life.

Feature of the present utility model is that the outside, original motor cycle rear wheel rim center is added the system tie-plate, but tie-plate lateral surface spiral shell connects the disc brake brake disc, in the step axis hole of tie-plate center the gusset piece assembly can be installed.

Above-mentioned tie-plate axis hole is greater than rear rim axle drive shaft axis hole.

Above-mentioned tie-plate is connected with existing rear rim screw.

Above-mentioned tie-plate can be cast into one with rear rim.

Block bearing in the gusset piece assembly adopts entad globe bearing of biserial.

The utility model has solved the difficult problem that disc brake brake disc and double damper are installed owing to add the system tie-plate in the outside, rear rim center on original drum-braking typed wheel rim.And do not change the former drum installation site of stopping, both disc brake can be installed separately, and drum also can be installed simultaneously stop, particularly the hydraulic structure of disc brake can be equipped with the ABS anti-skid brake system, greatly improved safety performance, be high-grade luxurious the desirable rear rim of big-and-middle discharge capacity motor bike.

Description of drawings:

Fig. 1 is existing rear rim and johning knot composition thereof, 1-wheel rim wherein, 2-driving engine left crankcase, the 3-bearing, 4-axle drive shaft, 5-bearing, 6-gusset piece assembly, 7-retaining nut, 8, the 9-bearing, the 10-drum chamber Fig. 2 that stops is the utility model assembly type rear rim and johning knot composition thereof, 8-1303 bearing wherein, the 11-tie-plate, 12, the 13-screw, 14-disc brake brake disc.Fig. 3 is the utility model integral type rear rim and johning knot composition thereof, wherein 11-and rear rim casting all-in-one-piece tie-plate.Fig. 4 is an integral type rear rim front view.Fig. 5 is Fig. 4 A-A section drawing.Fig. 6 is an assembly type rear rim front view.Fig. 7 is Fig. 6 B-B section drawing.

The specific embodiment:

With reference to Fig. 2, Fig. 7.In existing rear rim drum chamber 10 bottom opening of stopping, pass outwards through for screw 12, and captive joint with tie-plate 11b face, tie-plate 11a face connects disc brake brake disc 14 with screw 13 spiral shells, gusset piece assembly 6 penetrates tie-plate 11 axis holes and is connected with engine drive axle 4 by retaining nut 7, and its centre bearer 8 adopts entad globe bearing of 1303 type biserials, has aligning performance preferably, allow 2-3 degree Internal and external cycle relative tilt, make the gusset piece elimination that swings.Because the utility model adds system tie-plate 11, needs long drive shaft 4 a little, and right back bumper is installed on the gusset piece, realize two rear shock absorbers.For wheel rim manufacturing enterprise, wheel rim and tie-plate 11 can be cast into one with reference to Fig. 3, Fig. 5, structure is more firm.Tie-plate axis hole 11 ' greater than the axle drive shaft axis hole, but connect disc brake brake disc 14 with screw 13 spiral shells.
