Abstract
The utility model provides a rear-arranged bus chassis frame. A left longitudinal beam and a right longitudinal beam are respectively of a whole structure punched at a time, the left longitudinal beam is of a Z-shaped structure in the longitudinal direction, the right longitudinal beam is of an n-shaped structure in the longitudinal direction, and therefore a connection structure that the front section of the left longitudinal beam is high and the front section of the right longitudinal beam is low is formed; a first transverse beam of the chassis frame is in a Z shape with a high left portion and a lower right portion and is connected with the left longitudinal beam and the right longitudinal beam; the left longitudinal beam is vertically connected with a connection support, a second transverse beam of the chassis frame is connected with the lower end of the connection support, and the other end of the second transverse beam is connected with the right longitudinal beam. According to the rear-arranged bus chassis frame, the longitudinal beam whole has better bearing performance than a segmented lap joint longitudinal beam, and weight is also reduced by 15%-20%; manufacturing cost of the chassis frame is reduced. The front structure makes the whole driver seat be at a high position, a front door step is relatively lowered, design of a front wheel arch is considered, the height of the whole bus is reduced, a front and middle segmented connection mode in the past is omitted, design of a side operation platform of a driver is facilitated, and passengers get on and off the bus conveniently.
Description
Technical field
The utility model relates to the rearmounted public transport chassis frame that a kind of length is 7-10 rice.
Background technology
Before the current chassis of domestic rearmounted public transport in the past, mark time and locate the symmetrical formula overlapping mode of the many employings of structure in operator's compartment and Qianmen, longeron mostly is bathtub construction, adopt bending technique, then connect with tie-beam, form left and right drop, as Fig. 1, shown in Fig. 2, left longeron is by left front lower longeron 6, left front upper longeron 3 forms with left floor side member 4 overlap joints, right vertical beam is by front right longitudinal beam 1, middle tie-beam 5 forms with right floor side member 2 overlap joints, left longeron and right vertical beam connect and compose vehicle frame by multiple crossbeams, with vehicle frame first crossbeam and second cross beam and the left front lower longeron 6 of direction from front to back, front right longitudinal beam 1 connects, form left and right drop, the body frame structure for automotive of this structure is quite complicated, the tie bolt needing is also many, waste is serious, assembling difficulty, cost rises, vehicle frame integral structure is comparatively loose, and the design of front operator's station must increase higher operator's station on vehicle frame just can make operator's saddle in a relative high position.In addition, car load factory structural arrangement is also brought to difficulty, be also unfavorable for the reduction of cost.
Summary of the invention
The purpose of this utility model is the bridging arrangement that changes current this rearmounted public transport chassis frame complexity, in line with saving, applicable, failure-free principle, proposes a kind of rearmounted public transport chassis frame, the disposable stamping forming overall plan of special-shaped longeron before and after adopting.
For this reason, the technical solution of the utility model is: a kind of rearmounted public transport chassis frame, formed by left longeron, right vertical beam, many connecting cross beams, it is characterized in that: left longeron and right vertical beam are all disposable stamping forming integral structures, left longeron is longitudinally being " Z " font structure, right vertical beam is longitudinally being "Ji" type structure, thereby forms the connection structure that left longitudinal beam front section is high, right vertical beam leading portion is low; The Z-shaped that the first crossbeam structure of vehicle frame is right low left high, is connected with left-right longeron; A sagging connection bracket on left longeron, the second cross beam of vehicle frame is connected with connection bracket lower end, and the other end of second cross beam is connected with right vertical beam.
Beneficial effect: clearly, the utility model integral type longeron is more far better than the load of segmentation bridging type longeron, weight is also light 15-20%; The manufacturing cost of vehicle frame reduces, and production efficiency improves, and every bogie frame is just saved up to a hundred with regard to one, bolt, makes complete vehicle structure more reasonable, smooth, makes chassis member assembling more reliable, has alleviated the weight of car load.Front structure has been taken into account car load operator's saddle relatively in a high position, and mark time and relatively reduce in Qianmen, taken into account the design of front-wheel arch simultaneously, car load height reduces, break with forward, stage casing connection segment mode, be conducive to the design of driver's side operation bench, be conducive to the easy for going up and down of passenger.

The specific embodiment
The rearmounted public transport chassis frame of one as shown in Fig. 4, Fig. 5, Fig. 6, formed by left longeron 8, right vertical beam 7, many connecting cross beams, left longeron 8 and right vertical beam 7 are all disposable stamping forming integral structures, left longeron 8 is longitudinally being " Z " font structure, right vertical beam 7 is longitudinally being "Ji" type structure, thereby forms the connection structure that left longitudinal beam front section is high, right vertical beam leading portion is low; The Z-shaped that first crossbeam 10 structures of vehicle frame are right low left high, is connected with left-right longeron; A sagging connection bracket 11 on left longeron, the second cross beam 9 of vehicle frame is connected with connection bracket 11 lower ends, and the other end of second cross beam 9 is connected with right vertical beam.
The explanation of described first crossbeam and second cross beam: with the direction from front to back of vehicle frame, many connecting cross beams are defined as: first crossbeam, second cross beam, the 3rd crossbeam ...
The utility model proposes a kind of rearmounted public transport chassis frame, left longeron and right vertical beam are all disposable stamping forming integral structures, left longeron is longitudinally being " Z " font structure, right vertical beam is longitudinally being "Ji" type structure, thereby forms the connection structure that left longitudinal beam front section is high, right vertical beam leading portion is low; The Z-shaped that the first crossbeam structure of vehicle frame is right low left high, is connected with left-right longeron; A sagging connection bracket on left longeron, the second cross beam of vehicle frame is connected with connection bracket lower end, and the other end of second cross beam is connected with right vertical beam.The utility model integral type longeron is more far better than the load of segmentation bridging type longeron, weight is also light 15-20%; The manufacturing cost of vehicle frame reduces.Front structure has been taken into account car load operator's saddle relatively in a high position, and mark time and relatively reduce in Qianmen, taken into account the design of front-wheel arch simultaneously, car load height reduces, break with forward, stage casing connection segment mode, be conducive to the design of driver's side operation bench, be conducive to the easy for going up and down of passenger.
