Description
Technical field
It is leading to the balanced support wheel apparatus to the present invention relates to a kind of chassis of trailer, belongs to technical field of engineering machinery.
Background technology
The unpowered mechanism of trailer self needs during work to be connected with tractor truck, under the tractor truck effect, realizes operation, breaks away from the back with tractor truck and leans on manpower to promote, and also needs simultaneously it is carried out balanced support, to stop safety misadventure.In the production process,, also to articulate disengaging with tractor truck even need it to implement the short range operation, very inconvenient.
Summary of the invention
The objective of the invention is provides a kind of chassis of trailer leading to the balanced support wheel apparatus to the problems referred to above, mainly is when trailer and tractor truck disengaging, is used to support trailer, can realize that the short range manpower tows simultaneously.
For achieving the above object, the present invention adopts following technical scheme:
It is leading to the balanced support wheel apparatus to invent said chassis of trailer; Form by hasp hook, device urceolus, anchor fitting, suspension gear, telescoping mechanism, device inner core and cardan wheel assembly; Said hasp hook and anchor fitting are installed on relevant position on the device urceolus; In the device inner core one end charging apparatus urceolus, telescoping mechanism is installed on the end that is connected of device urceolus and device inner core, and the connecting panel end of the device inner core other end and said cardan wheel assembly flexibly connects; The connecting panel of said cardan wheel assembly is provided with the connection hasp; Said suspension gear is fixed in the Trailer type frame for use in vehicle relevant position, and with the corresponding connection of hasp hook, anchor fitting and Trailer type frame for use in vehicle relevant position flexibly connect.
Said telescoping mechanism is a four-bar linkage; One end of four connecting rods is captiveed joint with inner/outer tube coupling end both sides respectively; The other end flexibly connects through rotating shaft in twos; Four connecting rods, one movable rotation-shaft is equipped with a threaded block outward, through this threaded block the screw mandrel in tape spool hole, one end is housed between two movable rotation-shafts, and the dwang of being convenient to pack into rotates regulates four-bar linkage.
Adopt the beneficial effect of technique scheme to be.
1, simple in structure, easy to operate;
2, when trailer and tractor truck break away from, be used for supporting, the balance trailer, and can realize the short-range transhipment of trailer, make things convenient for trailer to use and take care of;
3, act freely, reliability is high, easy care.
Description of drawings
Fig. 1 is leading to balanced support wheel construction scheme drawing for chassis of trailer of the present invention;
Fig. 2 is the birds-eye view after the present invention is installed on Trailer type frame for use in vehicle;
Among the figure: 1-hasp hook, 2-device urceolus, 3-anchor fitting, 4-suspension gear, 5-telescoping mechanism, 6-device inner core, 7-connect buckle, 8-cardan wheel, 9-screw mandrel, 10-threaded block.
The specific embodiment
The contrast accompanying drawing is done further explain to the present invention below.
As shown in the figure; Chassis of trailer of the present invention is leading to be made up of hasp hook 1, device urceolus 2, anchor fitting 3, suspension gear 4, telescoping mechanism 5, device inner core 6, cardan wheel assembly 8 to the balanced support wheel apparatus; Said hasp hook 1 is installed on relevant position on the device urceolus with anchor fitting 3; In the device inner core 6 one end charging apparatus urceolus 2, telescoping mechanism 5 is installed on the end both sides that are connected of device urceolus and device inner core, and the connecting panel end of device inner core 6 other ends and said cardan wheel assembly 8 flexibly connects; The connecting panel of said cardan wheel assembly 8 is provided with and connects hasp 7; Said suspension gear 4 is fixed in the Trailer type frame for use in vehicle relevant position, and with the 1 corresponding connection of hasp hook, anchor fitting 3 flexibly connects with the Trailer type frame for use in vehicle relevant position.
Said telescoping mechanism 5 is a four-bar linkage; One end of four connecting rods is captiveed joint with inner/outer tube coupling end both sides respectively; The other end flexibly connects through rotating shaft in twos; Four connecting rods, one movable rotation-shaft is equipped with a threaded block 10 outward, through this threaded block 10 screw mandrel 9 in tape spool hole, an end is housed between two movable rotation-shafts, and the dwang of being convenient to pack into rotates regulates four-bar linkage.
In the use, when trailer and tractor truck break away from, be connected hasp 7 on the hasp hook 1 that unclamps front end and the cardan wheel connecting panel; Cardan wheel 8 places ground, is used to support trailer, packs the dwang that is equipped with in screw mandrel 9 holes of telescoping mechanism 5 into; The relative position of device for regulating rotary urceolus 2 and device inner core 6; Thereby regulate bearing height, guarantee that chassis of trailer is in horizontality, and can realize that short-range manpower tows Trailer type frame for use in vehicle; And when trailer is connected with tractor truck; Through rotational fixation device 3 balanced support wheel apparatus of the present invention is placed the Trailer type frame for use in vehicle parallel position; Through hasp hook 1 with suspension gear 4, is connected hasp 7 and cardan wheel 8 is turned over overhead with articulating of tractor truck relevant position, be fixed in Trailer type frame for use in vehicle and draw the vehicle frame bottom and move with tractor truck.
