This brake system also comprises the indicating device that instruction vehicle is in release of brake state, this indicating device comprises the first indication piece 211 being located at car body 20 opposite side, first indication piece 211 links with drag chain 202, then can with the first indication piece 211 action of motor vehicles bodies 20 opposite side when drag chain 202 tightens up or relaxes.For succinct description, the side in literary composition, car body 20 being arranged drag chain 202 is called " chain side ", and the opposite side not arranging drag chain 202 is called " non-chain side ", then the first indication piece 211 is located at non-chain side.
Particularly, this indicating device also comprises transmission arm 23, and to be installed on car body 20 and across the rotating shaft 22 of car body 20 both sides, can understand see Fig. 4 and Fig. 6-8, Fig. 6 is the structural representation sketch of car brakeing relieved state indicating device provided by the present invention; Fig. 7 be the A of Fig. 6 to diagram, this indicating device instruction vehicle be in braking mode; Fig. 8 is the structure diagram that in Fig. 7, indicating device instruction vehicle is in relieved state.Because rotating shaft 22 is journaled on car body 20, then rotating shaft 22 can be rotated around the axis of himself.
Transmission arm 23 is arranged at chain side, one end of rotating shaft 22 is positioned at chain side, then one end of transmission arm 23 can be connected with rotating shaft 22 end of chain side, the other end of transmission arm 23 can be connected with drag chain 202, due to the chain structure of drag chain 202, transmission arm 23 can be connected with drag chain 202 by small slide 231, and as shown in Figure 5, small slide 231 can realize transmission arm 23 very easily and be connected with the reliable of drag chain 202.The other end of rotating shaft 22 is positioned at non-chain side, and the first indication piece 211 of non-chain side can be connected with rotating shaft 22 end of non-chain side, please refer to Fig. 5, Fig. 9-10, Fig. 9 be the B of Fig. 6 to diagram, this indicating device instruction vehicle be in braking mode; Figure 10 is the structure diagram that in Fig. 9, indicating device instruction vehicle is in relieved state.Visible, in this embodiment, the first indication piece 211 of non-chain side can realize linking with drag chain 202 by rotating shaft 22 and transmission arm 23.
Vehicle is arranged after comprising the brake system of above-mentioned indicating device, when operating personal rotates the braking hand-wheel 201 of either side, drag chain 202 can correspondingly tighten up or relax, and tightening up or relaxing of drag chain 202 can drive transmission arm 23 and rotating shaft 22 to rotate, the rotation of rotating shaft 22 has then correspondingly driven the rotation of the first indication piece 211 being positioned at the non-chain side of car body 20.When then drag chain 202 is in and tightens up and relax two states, the position of the first indication piece 211 is different.When operating personal is in non-chain side, can by checking that the position of the first indication piece 211 being positioned at non-chain side learns that vehicle is in braking or relieved state in time, during guarantee vehicle operating, drag chain 202 is in the state of relaxing, namely vehicle is in relieved state, avoids car brakeing to run and the serious accident such as wheel flat, derailing that causes; Correspondingly, whether operating personal, when non-chain side rolling brake handwheel 201 is braked or alleviates, can put in place by checking that the location learning of the first indication piece 211 is braked or alleviated.
Certainly, although in above-described embodiment the shift in position of the first indication piece 211 can characterize vehicle be in braking relieved state, but when operating personal does not learn the principle of work of this indication piece, the sign effect of indication piece is not directly perceived.Therefore further improvement can be made to a upper embodiment, as shown in Fig. 5,9-10, the indicating device in brake system also comprises the first display panel 241, first display panel 241 being arranged at the non-chain side of car body 20 and matches with the first indication piece 211.First display panel 241 subscript is marked with drag chain 202 and is in state of tightening up and relax, and what the first indication piece 211 can be driven when rotating shaft 22 is rotated to point on the first display panel 241 drag chain 202 of mark tightens up status indicator or the status indicator that relaxes (or the braking mode mark of vehicle and alleviate status indicator).As figure 5 illustrates, can mark " ON " and " OFF " on the first display panel 241, " ON " mark represents braking, and " OFF " mark represents to be alleviated.Obviously, after the first display panel 241 is fixed on car body 20, when drag chain 202 tightens up, the first indication piece 211 should point to the position the first display panel 241 marking " ON "; Correspondingly, when drag chain 202 relaxes, the first indication piece 211 rotates and change of location, and its another location pointing to the first display panel 241 should be mark " OFF " position.Now, the first indication piece 211 is equivalent to the pointer realizing with drag chain 202 linking, then the marked content that operating personal can indicate according to the first indication piece 211 learns that vehicle is in braking or relieved state intuitively.Mark " ON " and " OFF " in this embodiment, can expect, mark other marks and be also fine, such as directly to substitute " ON " and " OFF " with " braking " and " alleviation ".
