Abstract
The invention discloses a torque-adjustable turnover mechanism for a cab, which relates to the technical field of the turnover mechanism for the cab. The turnover mechanism comprises an adjustable turnover assembly and a support rod assembly, wherein the adjustable turnover assembly is connected with the support rod assembly. The torsion bar spring of the adjustable turnover assembly is arranged in the front bearing shaft pipe. One end of the torsion bar spring is fixed on a right bracket through a torsion bar arm and the other end is fixed on the spline end of the front bearing shaft pipe. The two ends of the front bearing shaft pipe are respectively provided with an open block ring. The support rod assembly is respectively fixed on a vehicle frame and the cab through the lower bracket of the support rod and the upper bracket of the support rod. The upper support rod is hinged with the lower support rod through a pin shaft. A lock arm and a pull spring are arranged at the joint of the lower support rod and the upper support rod. The lower support rod is fixed on the vehicle frame through the lower bracket of the support rod. Because adjusting bolts are arranged on the right bracket of the torque-adjustable turnover mechanism, the working angle of the torsion bar can be changed through screwing the adjusting bolts; and the problem that the torsion force of the turnover mechanism is reduced, which caused by the torsion attenuation of the torsion bar, can be solved.

Background technology:
Maintenance and maintenance for the ease of car load; Present most of COE truck operator's compartment generally can overturn forward; The form of its switching mechanism mainly contains hydraulic gear and torsion bar mechanism, and than hydraulic gear, torsion bar mechanism has characteristics such as layout is easy, simple to operate flexibly, reliability height.The upset of operator's compartment should be light, and the supporting device of operator's compartment should be safe and reliable.In order to guarantee vehicle safety travel, under normal conditions, especially at emergency braking or when receiving bigger impulsive force, operator's compartment must not overturn voluntarily.
Most of upsets light-duty or the in-between car operator's compartment now mainly are that the gravitational moment of utilizing the twist moment of torsion bar to overcome operator's compartment realizes.Its structure type is mainly two torsion bar mechanisms and single torsion bar mechanism, and two torsion bars are mainly used in the bigger in-between car of operator's compartment quality, are characterized in that pretwist moment is big, and the operator's compartment left and right sides is stressed evenly but complex structure, and operator's compartment bottom slab stress Da Yi produces distortion etc.Single torsion bar is mainly used in the little Light-duty Vehicle of operator's compartment quality; Be characterized in that pretwist moment is little relatively, but simple in structure, operator's compartment base plate left and right sides skeleton discontinuity; And traditional single torsion bar switching mechanism is because torsion bar is in the large angle torsion state for a long time; As time goes on, torsion bar can produce fatigue, and torsion can progressively be decayed.
Summary of the invention:
The purpose of this invention is to provide the adjustable cab turning mechanism of torsion, it increases adjustable bolt on right support, can be through screwing the operating angle of adjustable bolt change torsion bar, the switching mechanism torsion decline defective that compensation causes because of the decay of torsion bar torsion.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: it is made up of adjustable overturning unit and strut assembly, and adjustable overturning unit is connected with the strut assembly.
Described adjustable overturning unit comprises adjustable bolt/nut, bolt/spring washer, torsion bar arm, right support, preceding supporting rubber cushion, preceding supporting central siphon, left socle, torsion bar spring and split washer; The supporting central siphon was inner before torsion bar spring was arranged on; The one of which end is fixed on the right support through the torsion bar arm; Supporting central siphon splined end before the other end is fixed on, preceding supporting central siphon two ends are provided with split washer, and adjustable bolt/nuts and bolt/spring washer withstands torsion bar arm side; Preceding supporting central siphon two ends are respectively arranged with right support and left socle, supporting rubber cushion before being provided with between right support and left socle and the preceding supporting central siphon.
Described strut assembly comprises strut lower bracket, lower supporting rod, bearing pin, hammerlock, extension spring, goes up strut and strut upper bracket; The strut assembly is separately fixed on vehicle frame, the operator's compartment through strut lower bracket, strut upper bracket; Last strut and lower supporting rod are hinged through bearing pin; The junction of lower supporting rod and last strut is provided with hammerlock and extension spring, and lower supporting rod is fixed on the vehicle frame through the strut lower bracket.
Described right support, left socle are fixed on the vehicle frame, and cab anchorage is on preceding supporting central siphon.
Principle of work of the present invention is: under the normal condition; Operator's compartment is locked on the vehicle frame through lockable mechanism (bearing pin, hammerlock, extension spring); This moment, torsion bar spring was reversed certain angle storage screen resilience by force, and last strut, lower supporting rod are in folding case of bending through bearing pin.
After lockable mechanism is opened; Under the effect of torsion bar spring screen resilience; Operator's compartment rotates around preceding supporting rubber cushion center through preceding bolster circumference of cannon bone, and last strut, lower supporting rod are through bearing pin, and expansion fully under the operator makes progress thrust; Hammerlock will be gone up strut under the extension spring effect, lower supporting rod pins, and driver's cab turnover puts in place.
The present invention increases adjustable bolt on right support, can be through screwing the operating angle of adjustable bolt change torsion bar, the switching mechanism torsion decline defective that compensation causes because of the decay of torsion bar torsion.
Description of drawings:
Fig. 1 is the structural representation of adjustable overturning unit among the present invention,
Fig. 2 is a mounting structure scheme drawing of the present invention.
The specific embodiment:
With reference to Fig. 1-2, this specific embodiment adopts following technical scheme: it is made up of adjustable overturning unit A and strut assembly B, and adjustable overturning unit A is connected with strut assembly B.
Described adjustable overturning unit A comprises adjustable bolt/nut 1, bolt/spring washer 2, torsion bar arm 3, right support 4, preceding supporting rubber cushion 5, preceding supporting central siphon 6, left socle 7, torsion bar spring 8 and split washer 9; Supporting central siphon 6 inside before torsion bar spring 8 is arranged on; The one of which end is fixed on the right support 4 through torsion bar arm 3; Supporting central siphon 6 splined end before the other end is fixed on, preceding supporting central siphon 6 two ends are provided with split washer 9, and adjustable bolt/nut 1 and bolt/spring washer 2 withstand torsion bar arm 3 sides; Preceding supporting central siphon 6 two ends are respectively arranged with right support 4 and left socle 7, supporting rubber cushion 5 before being provided with between right support 4 and left socle 7 and the preceding supporting central siphon 6.
