Abstract

The utility model relates to a flat fronted diesel truck chassis, which is applicable to a truck-mounted crane with a carrying capacity of 16 tons and is characterized in that a front double steering mechanism is assembled on the big crane with the carrying capacity of 12 to 16 tons; a distance between first and second shafts is 2660mm; the distance between second and third shafts is 3800mm; the distance between middle and back shafts is 1350mm; the reinforced steering mechanism is disposed between the first and second shafts of a carriage; a backrest crossbeam is mounted between the first and second shafts; a crossbeam is additionally provided between the second and third shafts; and an inner reinforcement plate is extended to achieve the last crossbeam between the second and third shafts. The flat fronted diesel truck chassis benefits enhancement of economic benefit and enrichment of variety of products and meets the requirement of domestic users of a large-tonnage 8X4 special truck-mounted crane transporter.

Description

Tack diesel oil truck chassis

Technical field

The utility model relates to a kind of tack diesel oil truck chassis, and it is a kind of Jiefang brand CA1313P7K2L11T4A2E type tack diesel oil truck chassis that can mate 16 tons of lorry-mounted cranes.

Background technology

According at present domestic and international special vehicle development, the oriented 16 tons of loop wheel machine Development Trend in truck-mounted crane chassis, but domestic temporary nothing is fit to the chassis of the big loop wheel machine of repacking; Simultaneously, each truck-mounted crane originating firm also all proposes the demand to special-purpose 8 * 4 truck-mounted crane chassis; The two front axle wheelbase spaces (1900mm) of existing J5M 8 * 4 load-carrying vehicles are little, and the loop wheel machine profile increases, and loop wheel machine can't be arranged.Cross two front axles like loop wheel machine and arrange backward, the one, container loading space capable of using is extremely low, and the 2nd, cause that distribution of axle load is seriously unreasonable; The two front axle wheelbase 2660mm of existing J5M platform CA1253P7K2L11T3E 6 * 2 truck with loading cranes, though can satisfy the space, this car is a single drive shaft; Often fall into car in the building site; Needing increases axle drive shaft quantity, has both improved and has adhered to propulsive effort, can improve the charge material amount again; Existing platform CA1253P7K2L11T3E 6 * 2 loop wheel machines that truck with loading crane is joined are the 6.3-8 ton, and two front axle wheelbases space need arrange again that silencer and two axle steer rocking arms are to adapt to the layout of 16 tons of loop wheel machines.

Summary of the invention

The purpose of the utility model provides a kind of tack diesel oil truck chassis, is fit to the equipped big loop wheel machine of 12-16 ton, connects drive axle with φ newly developed 435 duplexs and replaces φ 457 duplexs perforation drive axle etc., and cost-cutting reduces deadweight 200 ㎏; Captured since the vehicle frame stress concentration that the loop wheel machine load concentration causes, suspension and front axle weak, turn to a series of difficult problems such as painstaking and double steering shaft inaccurate coordination.

The technical scheme of the utility model is achieved in that tack diesel oil truck chassis, can mate 16 tons of lorry-mounted cranes, it is characterized in that: preceding dual rotation i.e. one, two wheelbase is 2660 ㎜, and is equipped with the big loop wheel machine of 12-16 ton; Two, three wheelbase is 3800 ㎜; The wheelbase of middle rear axle is 1350mm, and vehicle frame one, two between centers are provided with the heavier-duty steering hardware, and at one, two between centers the dos-crossbeam is installed, and two, three between centers increase by a crossbeam; Interior brace panel extends to last crossbeam place of two, three.

The good effect of the utility model is that it combines the distribution of axle load rate according to four load-carrying vehicle chassis frame buttress bracing struts continuous modification characteristics, at the definite 2660+3800+1350 ㎜ wheelbase of principle calculating that guarantees that distribution of axle load is even, wear on tyres is balanced; Vehicle frame rigidity and intensity be can improve, loop wheel machine job stabilization and carrying capacity of chassis guaranteed; Having increases economic benefit, expands product variety, satisfies the special-purpose truck with loading crane user's of domestic large-tonnage 8X4 demand.

Fig. 2 is one, two interaxle novel steering mechanism structure scheme drawings.

Fig. 3 is the complete vehicle structure scheme drawing of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is done further description: like Fig. 1, the diesel oil of tack shown in 2 truck chassis; Can mate 16 tons of lorry-mounted cranes; It is characterized in that: preceding dual rotation i.e. one, two wheelbase 1 is 2660 ㎜, and is equipped with the big loop wheel machine of 12-16 ton; Two, three wheelbase 2 is 3800 ㎜; The wheelbase 3 of middle rear axle is 1350mm, and vehicle frame one, two between centers are provided with heavier-duty steering hardware 4, and increases by a crossbeam 6 at one, two between centers installation dos-crossbeam 5, two, three between centers; Interior brace panel 7 extends to last crossbeam place of two, three.

As shown in Figure 3, preceding double steering shaft wheelbase is 2660 ㎜, adopts this wheelbase can rationally adjust one, two distribution of axle load, prevents that the tire premature wear from appearring in unbalance stress; Secondly can satisfy the requirement of big loop wheel machine installing space more than 16 tons.The car load wheelbase is 2660+3800+1350, can make car load under the full-loading condition situation, not because of the excessive car load stress concentration that causes of the local counterweight of loop wheel machine; Each distribution of axle load rate is: one, two account for 37%; Three, four account for 63%, and one, two axle load is approximately equal, and three, four axle loads equate.

Claims

1. 16 tons of lorry-mounted cranes can be mated in tack diesel oil truck chassis, it is characterized in that: preceding dual rotation i.e. one, two wheelbase is 2660 ㎜, and is equipped with the big loop wheel machine of 12-16 ton; Two, three wheelbase is 3800 ㎜; The wheelbase of middle rear axle is 1350mm, and vehicle frame one, two between centers are provided with the heavier-duty steering hardware, and at one, two between centers the dos-crossbeam is installed, and two, three between centers increase by a crossbeam; Interior brace panel extends to last crossbeam place of two, three.
