Abstract

The utility model relates to a narrow round special limit disk front axle of school bus, including H -beam, stopper, brake chamber, wheel limit structure and knuckle, the both ends of H -beam connect the knuckle respectively, the knuckle outside is provided with the stopper, the stopper be disc brake, a limit structure is had in the setting of the stopper outside, the knuckle on set up brake chamber, brake chamber is connected with the stopper. The utility model discloses a super narrow wheel limit structure, the biggest outer width only is 1900mm, the effectual track that shortens school bus front axle to satisfy the school bus at road traveling needs such as rural narrow road and city narrow lanes, simultaneously, the utility model discloses a disc brake, disc brake braking effect is good, improves the security performance of school bus, in addition, the utility model discloses a H -beam adopts the recessed structure in middle part to distance between effectual increase wheel axle center and the H -beam top surface, increase axle drop reduces school bus floor height, makes things convenient for the student to get on or off the bus.

Description

School bus is special narrowly takes turns limit disc-type front axle
technical field:
The utility model relates to special school bus technical field of structures, is specifically related to that a kind of school bus is special narrowly takes turns limit disc-type front axle.
background technology:
Along with the raising of people's awareness of safety, the attention of people to safety of student also improves gradually, is specifically designed to the school bus that student takes, arises at the historic moment.But, school bus on existing market is convert from some old money passenger vehicles mostly, or directly old money vehicle is used as school bus use, and its partial function can not meet the needs of school bus, and cost is higher, school bus mainly for passenger be child, safety be topmost, also require traveling comfort in addition, existing school bus substantially width is all wider, basically identical with passenger vehicle width, in some rural highways or urban streets and lanes because road is narrower, not easily pass through.Cause a lot of special school bus to enter rural market, cause rural market school bus irregular, safety misadventure takes place frequently, and causes all circles to pay much attention to.
At present, the H-girder of the propons that market colonel is automobile-used and steering swivel are all H-girder and the steering swivel of the propons of light truck, its safety factor obviously cannot meet the needs of special school bus, and, what existing school bus propons adopted is all drum-type structure drg, the brake wheel annular of drum brake mechanism surrounds brake shoe brake cheek and friction lining, form confined space, drg is caused to dispel the heat bad, hot environment easily causes again friction disc brake power to fail, and uses and brings potential safety hazard, in addition to school bus, existing school bus front axle wheel, apart from wider, can not meet rural area narrow road needs.
utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides that a kind of school bus is special narrowly takes turns limit disc-type front axle, it adopts the wheel limit structure of ultra-narrow, maximum outer be widely only 1900mm, actv. shortens the wheelspan of school bus propons, thus meet school bus at road driving needs such as the narrow lanes of rural area narrow road and city, simultaneously, the utility model adopts plate disc brake, Disk Brake is effective, improve the safety performance of school bus, in addition, the structure that H-girder of the present utility model adopts middle part recessed, thus actv. increases the distance between axis wheel and H-girder end face, increase vehicle bridge drop, reduce school bus floor level, student is facilitated to get on or off the bus.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of school bus is special narrowly takes turns limit disc-type front axle, wherein: comprise H-girder, drg, compressed air brake cylinder, wheel limit structure and steering swivel, the two ends of described H-girder connect steering swivel respectively, steering swivel arranged outside has drg, drg is plate disc brake, drg arranged outside has wheel limit structure, and described steering swivel arranges compressed air brake cylinder, and compressed air brake cylinder is connected with drg.
Further, described H-girder is the H-girder of the high concave configuration in low two ends, middle part, and the distance after installing between H-girder and axis wheel is 95mm.
Further, the distance between two wheel limit structure outermost end of described H-girder both sides is 1900mm.
The beneficial effects of the utility model are:
The utility model adopts the wheel limit structure of ultra-narrow, maximum outer be widely only 1900mm, actv. shortens the wheelspan of school bus propons, thus meet school bus at road driving needs such as the narrow lanes of rural area narrow road and city, simultaneously, the utility model adopts plate disc brake, Disk Brake is effective, improve the safety performance of school bus, in addition, the structure that H-girder of the present utility model adopts middle part recessed, thus actv. increases the distance between axis wheel and H-girder end face, increase vehicle bridge drop, reduce school bus floor level, facilitate student to get on or off the bus.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of school bus is special narrowly takes turns limit disc-type front axle, comprise H-girder 1, drg 2, compressed air brake cylinder 3, wheel limit structure 4 and steering swivel 5, the two ends of described H-girder 1 connect steering swivel 5 respectively, and steering swivel 5 arranged outside has drg 2, and drg 2 is plate disc brake 2, drg 2 arranged outside has wheel limit structure 4, described wheel limit structure 4 is narrow limit structure 4 of taking turns, and described steering swivel 5 is arranged compressed air brake cylinder 3, compressed air brake cylinder 3 is connected with drg 2.H-girder 1 is the H-girder 1 of the high concave configuration in low two ends, middle part, and the distance after installing between H-girder 1 and axis wheel is 95mm.Distance between two wheel limit structure 4 outermost end of described H-girder 1 both sides is 1900mm.
The utility model adopt plate disc brake 2 as school bus propons brake equipment, plate disc brake 2 good braking effect, improve the safety performance of school bus, distance between two wheel limit structure 4 outermost end of the present utility model is 1900mm, thus actv. shortens school bus wheelspan, meet school bus at road driving needs such as the narrow lanes of rural area narrow road and city, the distance between H-girder 1 and axis wheel is 95mm, be conducive to reducing school bus floor level, facilitate student to get on or off the bus.
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.
