Description
Technical field
The utility model belongs to amphibious vehicle field, particularly relates to a kind of jack of amphibious vehicle wheel draw off gear.
Background technology
Amphibious vehicle because can travel on land, again can in water before so that of many uses, be mainly used in military field at present.Need when the wheel of amphibious vehicle travels on land to support on the ground, and dependence being advanced with the friction force on ground, then needs to accept when advancing in water in order to reduce resistance, so just needing on amphibious vehicle, design a kind of wheel draw off gear.
Some are had to patent document discloses the jack of the amphibious vehicle wheel draw off gear of various structures form, as US5590617, US4958584 and ZL200810018848.1 at present.Wherein US5590617 and US4958584 is top bumper being arranged on Top Crossbeam, will take larger car load space like this, thus cause vehicle's center of gravity to raise, and reduces stability when travelling, and increases the trend of body roll.Structure described in ZL200810019948 is then placed in bumper between Top Crossbeam and lower cross arm, and bumper upper end is positioned at the outside below it, and the jack that this draw off gear adopts is linkage rod slide block mechanism, it controls the folding and unfolding angle of wheel in the motion of guide rail by slide block, the defect of this jack is that folding and unfolding angle is large not; In order to ensure that enough large folding and unfolding angle only has again the volume increasing whole jack, jack will be caused so too fat to move.
Utility model content
The amphibious vehicle wheel draw off gear jack that technical problem to be solved in the utility model is to provide a kind of compact conformation, compact, folding and unfolding angle can be enough large.
The technical solution of the utility model is as follows: a kind of jack of amphibious vehicle wheel draw off gear, it is characterized in that: comprise chassis assembly (1) and upper bulb bearing (16), wherein second journal stirrup (12) of chassis assembly (1) bottom is hinged with the inner of lower cross arm (9) by the 3rd bearing pin (11), the outer end of this lower cross arm is by a lower bulb bearing (13) and goat's horn (14) middle part swivel coupling, and the bottom of goat's horn (14) is used for installing wheel assembly (15); Rotating shaft end and goat's horn (14) top of described upper bulb bearing (16) are fixed, on this, the forward and backward side of bulb bearing case is coaxially provided with a semiaxis (16a), and these two semiaxis are positioned at the inner side of described lower bulb bearing (13); Semiaxis (16a) described in every root by lining in the shell-like portion of Top Crossbeam (17) outer end, this semiaxis is locked by a lock screw (18) of correspondence, and Top Crossbeam the inner is hinged with the 3rd journal stirrup (20) on described chassis assembly (1) top by the 4th bearing pin (19), and chassis assembly (1), lower cross arm (9), goat's horn (14) and Top Crossbeam (17) form a four-bar linkage; When described wheel set (15) needs folding, control lower cross arm (9) upwards to rotate around the 3rd bearing pin (11), this lower cross arm (9) drives Top Crossbeam (17) upwards to rotate around the 4th bearing pin (19) by goat's horn (14), and then realizes the folding of wheel set (15).
In technique scheme, when described wheel set (15) needs folding, control lower cross arm (9) upwards to rotate around the 3rd bearing pin (11), this lower cross arm (9) drives Top Crossbeam (17) upwards to rotate around the 4th bearing pin (19) by goat's horn (14), and then realizes the folding of wheel set (15).Simultaneously, because the pendulum angle of Top Crossbeam during folding and unfolding (17) is larger than lower cross arm (9), and the pendulum angle scope of general bulb bearing is 0 °-25 °, so two semiaxis (16a) have been set up in this case on the basis of upper bulb bearing (16), every root semiaxis (16a) by lining in the shell-like portion of Top Crossbeam (17) outer end, so just significantly increase the angle that Top Crossbeam (17) can swing, after above-mentioned design, the pendulum angle of Top Crossbeam (17) can reach 0 °-180 °, thus can meet the functional requirement of folding and unfolding.In addition, the chassis assembly (1) of this case, lower cross arm (9), goat's horn (14) and Top Crossbeam (17) form a four-bar linkage, synchronous hunting during this four parts folding and unfoldings, thus complete folding and unfolding, and the structure of this four-bar linkage is simple, compact, compact, has so just saved a lot of space, particularly compared with traditional connecting rod slider-type structure, thus be very easy to arrangement.
Adopt above technical scheme, the utility model has enough large folding and unfolding angle, and compact conformation, compact, has good practicality and reliability, is suitable for extensively promoting the use.
As optimal design, described lower cross arm (9) is " A " character form structure, and the termination of this lower cross arm dual-side is respectively equipped with described 3rd bearing pin (11); Described Top Crossbeam (17) is " H " shape structure, two described semiaxis (16a) are located in the shell-like portion of this Top Crossbeam dual-side outer end respectively, and the inner of Top Crossbeam (17) dual-side is respectively equipped with described 4th bearing pin (19); Described goat's horn (14) is " A " character form structure, and its connection side is provided with described lower bulb bearing (13).
Adopt above unitized design, the utility model can not only ensure structural strength, but also effectively reduces the space shared by the utility model, makes the miniaturization of this draw off gear, thus is convenient to arrangement further.
Beneficial effect: the utility model has enough large folding and unfolding angle, and compact conformation, compact, has good practicality and reliability, is suitable for extensively promoting the use.
