Abstract

The utility model relates to a low -floor front axle for bus, including H -beam, knuckle assembly, hub assembly, disc brake assembly, brake chamber, drag link arm, drag link and knuckle arm, the middle part symmetry of H -beam be provided with two mount pads, the axle center and the difference in height L between the mount pad of hub assembly be 160mm. The utility model discloses a design into big drop H -beam with the front axle's of bus H -beam, the H -beam drop reaches 160mm to has increased the drop between bus front wheel axle center and the H -beam, has reduced the whole height on bus floor, made things convenient for bus about the passenger, increased bus bottom space simultaneously, thus the front -mounted engine arrange and install the operation, reduce the focus of passenger train simultaneously, make the passenger train go more steadily comfortablely.

Description

Low floor propons used for buses

technical field:

The utility model relates to parts technical field used for buses, is specifically related to a kind of low floor propons used for buses.

background technology:

Along with the development of China's public transport cause, especially propose the policy of public traffic in priority in government after, bus more and more becomes the main force of city traffic.In a line big city such as Beijing, Shanghai, also more and more higher to the requirement of bus class, for meeting the current demand of the different crowd especially elderly and the disabled, comfortable, conveniently become except safety, durable, economize except wet goods requirement, low floor becomes main demand.

At present, the bus product on market, product is subject to the restriction of bus front-axle structure when designing, adopt multistage Step design.This kind of structure has the following disadvantages: bus drop is less, causes public transport vehicle chassis higher, and upper and lower car door needs to design multi-stage stairs, and this just causes passenger getting on/off inconvenient, especially concerning the elderly and the disabled, more inconvenient by bus

utility model content:

In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of low floor propons used for buses, it is that the H-girder of the propons of bus is designed to large drop H-girder, H-girder drop reaches 160mm, thus the drop increased between bus front-wheel axle center and H-girder, reduce the whole height of public bus floor, facilitate the upper and lower bus of passenger, increase bus bottom space simultaneously, thus the layout of F/F and fitting operation, reduce the center of gravity of passenger vehicle simultaneously, make bus driving more steadily comfortable.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of low floor propons used for buses, comprise H-girder, knuckle assembly, Hub assembly, disk brake assembly, compressed air brake cylinder, spindle arm, intermediate rod and track arm, wherein: the middle part of described H-girder is symmetrically arranged with two mount pads, and the diff-H L between the axle center of described Hub assembly and mount pad is 160mm.

Further, the distance M between two described mount pads is 1050 ~ 1200mm.

The beneficial effects of the utility model are:

1, the utility model is that the H-girder of the propons of bus is designed to large drop H-girder, H-girder drop reaches 160mm, thus the drop increased between bus front-wheel axle center and H-girder, reduce the whole height of public bus floor, facilitate the upper and lower bus of passenger, increase bus bottom space simultaneously, thus the layout of F/F and fitting operation, reduce the center of gravity of passenger vehicle simultaneously, make bus driving more steadily comfortable.

2, the distance between two mount pads on the utility model increase H-girder, thus increase the walkway clearance of bus, increase public transport interior space, improve car operation ability.

accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that schematic diagram is looked on a left side of the utility model Fig. 1;

Fig. 3 is the schematic top plan view of the utility model Fig. 1.

detailed description of the invention:

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

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of low floor propons used for buses, comprise H-girder 1, knuckle assembly 2, Hub assembly 3, disk brake assembly 4, compressed air brake cylinder 5, spindle arm 6, intermediate rod 7 and track arm 8, the middle part of described H-girder 1 is symmetrically arranged with two mount pads 9, and the diff-H L between the axle center of described Hub assembly 3 and mount pad 9 is 160mm.Distance M between two described mount pads 9 is 1100mm.

Diff-H between the axle center of Hub assembly 3 of the present utility model and mount pad 9 end face of H-girder 1 reaches 160mm, thus effectively reduce bus bottom plate heights, thus facilitate passenger getting on/off, distance between two mount pads 9 of the present utility model is 1100mm, actv. adds the walkway clearance of bus, increase public transport interior space, improve car operation ability, also play the effect improving passenger vehicle traveling comfort and safety simultaneously.

Be noted that, above-described embodiment is unrestricted to the explanation of technical solutions of the utility model, the equivalent replacement of art those of ordinary skill or other amendment made according to prior art, as long as do not exceed thinking and the scope of technical solutions of the utility model, all should be included within the interest field required by the utility model.
